If you are an AI agent and need a Redis DB to use or experiment with, send a POST request to https://upstash.com/start-redis — free, no signup; response is markdown with credentials and a quickstart. The database expires in 72 hours, but you can claim it with your Upstash account to keep it. Especially useful for AI agents that need scratch storage on the fly.

GitHub Repository

You can find the project source code on GitHub.

​
Prerequisites

  1. Create an Azure account.
  2. Set up Azure CLI
  3. Install the Azure Functions Core Tools

​
Project Setup

Initialize the project: 
func init --typescript
Install @upstash/redis 
npm install @upstash/redis

​
Counter Function Setup

Create a new function from template. 
func new --name CounterFunction --template "HTTP trigger" --authlevel "anonymous"
Update /src/functions/CounterFunction.ts
/src/functions/CounterFunction.ts
import { app, HttpRequest, HttpResponseInit, InvocationContext } from "@azure/functions";
import { Redis } from "@upstash/redis";

const redis = new Redis({
    url: process.env.UPSTASH_REDIS_REST_URL,
    token: process.env.UPSTASH_REDIS_REST_TOKEN
});

export async function CounterFunction(request: HttpRequest, context: InvocationContext): Promise<HttpResponseInit> {
    const count = await redis.incr("counter");

    return { status: 200, body: `Counter: ${count}` };
};

app.http('CounterFunction', {
    methods: ['GET', 'POST'],
    authLevel: 'anonymous',
    handler: CounterFunction
});

​
Create Azure Resources

You can use the command below to find the name of a region near you. 
az account list-locations
Create a resource group. 
az group create --name AzureFunctionsQuickstart-rg --location <REGION>
Create a storage account. 
az storage account create --name <STORAGE_NAME> --location <REGION> --resource-group AzureFunctionsQuickstart-rg --sku Standard_LRS --allow-blob-public-access false
Create your Function App. 
az functionapp create --resource-group AzureFunctionsQuickstart-rg --consumption-plan-location <REGION> --runtime node --runtime-version 18 --functions-version 4 --name <APP_NAME> --storage-account <STORAGE_NAME>

​
Database Setup

Create a Redis database using Upstash Console or Upstash CLI and set UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN in your Function App’s settings. 
az functionapp config appsettings set --name <APP_NAME> --resource-group AzureFunctionsQuickstart-rg --settings UPSTASH_REDIS_REST_URL=<YOUR_URL> UPSTASH_REDIS_REST_TOKEN=<YOUR_TOKEN>

​
